Q&A. The differences between an unadjusted trial balance and an adjusted trial balance are the amounts recorded as part of the adjusting entries. Adjusting entries include the accrual of revenues that were earned but were not yet recorded, and the accrual of expenses that were incurred but were not yet recorded.
The adjusted trial balance includes income from the current period. Closing entries reduce the income account to zero and transfer the balance to the income summary account. Each income account listed in the income summary balance contributes to total revenue for the period.
